Introduction to Plasma Physics by Francis Chen is probably one of the best sources for introductory plasma physics, despite being slightly dated (publication date of 1995) and using CGS units. It covers, among other things, particle motions in E&M fields plasmas as fluids (e.g., MHD) plasmas as particles (kinetic theory) controlled fusion As a ...

$\nabla\cdot\mathbf B=0$ does indicate that there are no magnetic monopoles, so there isn't a "starting" or "ending" point for field lines is mostly correct. So this must mean that magnetic field lines either form closed loops extend to infinity intersect the domain boundary (wall, stellar surface, etc) So the "starting & ending points" issue ...

One must be very careful in making the step from $\nabla\cdot\mathbf{B}=0$ to a statement such as "magnetic field lines do not start or end". Consider the field in the region of an X-point type magnetic null (in two dimensions). Take a 'volume' (i.e. an area) centred on the null point, and look at the field lines through the bounding curve. No matter how ...

Plasma wakefield acceleration works by introducing a driver into plasma and accelerating particles in its wake. The driver can either be a laser pulse or an electron beam. In both cases, the most common mechanism of acceleration is the so-called bubble (or blow-out/cavity) regime. This works by the driver pushing electrons in front of it while due to their ...
